WATER HEATER BOILER ATTACHMENT Application filed April 3, 1931. Serial No. 527,540. I

This invention relates to water heater boil er attachments and it has special reference to a novel head adapted to co-act with a plurality of groups of boiler tubes.

An object of the invention is the provision of a special type of head of the character described which is more efiicient than those heretofore provided.

ther objects will be apparent from a reading of the following specification, and especially to those skilled in the art.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawings which form part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawings nor to the precise construction described and, therefore, such changes and modifications may be made therefrom as do not aiiect the spirit of the invention nor exceed the scope thereof as expressed in the appended claim.

In the drawings:

Fig. 1 is a front elevation of a boiler and a water tank attached thereto showing three of the heads invented by us.

Fig. 2 is a fragmentary plan view of Fig. 1.

Fig. 3 is a horizontal View, partly in section and partly broken away of the boiler shown in Fig. 1.

Fig. 4 is a vertical section taken on line 44 of Fig. 3.

Fig. 5 is a section taken on line 5-5 of Fig. 4C; and

Fig. 6 is a section taken on line 66 of Fig. 4:.

Referring to the drawings for a more detailed description thereof, the numeral 7 indicates a boiler connected to a water tank 8. The cold water supplied to the boiler flows through pipes 10 and 11 into heads 12, t ir-ee of which are shown in Fig. 1. The heads 12 are all of the same construction and only one need be hereinafter described. Each of the heads 12 is connected to a plurality of groups of pipes by means of bolts 13 passing through a base plate 14 integral with the head and through a flange 15 of the boiler, all of the pipes which are connected to one head being shown in Figs. 5 and 6, and these stares" ParsNtossics groups may be collectively indicated by the numeral 17.

The cold water enters the heads 12 fromthe pipe 11 through pipes 19 which are each connected to the pipe 11 and to a head 12. A pipe 19 is clearly shown in Fig. 4 and is threaded to a head 12, communicating with a compartment 21 of the head into which cold water flows from the pipe 19. he Water flows from the compartment 21 into a group of pipes 23 indicated in Fig. 5 and issues therefrom into a tank 26 secured to pipes at the rear ends thereof. The water then flows back to the front of the boiler through a group of pipes 28 indicated in Fig. 5, and

into a compartment 30 of the head 12, after which it flows into a group of pipes 32 also shown in Fig. 5 and into a tank 3 1 offset from the tank 26. The water then flows towards the front part of the boiler through a group of tubes 36 into a compartment 37 of the head I 12 and out through a pipe 38 to a pipe 40 which is connected with the water tank 8. The pipe 40, as shown in Fig. 1, is connected with. all of the heads 12 by means of outlet pipes 38.

The invention described thus contemplates a plurality of heads for boiler tubes, each head having an inlet and an outlet and provided with a base plate attachable to a boiler and each head having a plurality of compartments adapted to cooperate with a plurality of groups of boiler tubes.

What is claimed as new is:

A device for the purpose indicated comprising a header formed with lower, intermediate and upper compartments and having a marginal flange for securing it in an opening in a boiler head, tubes extending from said header and arranged in groups of which one group communicates with each compartment of the header, and a housing connecting the a cold water inlet to the lower compartment and a hot water outlet from the upper compertinent, the housing enclosing the remote ends of the tubes having that portion placing the intermediate group in communication With the lower group more remote from the header than that portion placing the intermediate group in communication with the up er group. 7

n testimony whereof We hereby affix our signatures.
